TU-114

[louross]

In order to break away from the Screenshot thread, I moved over to here. First , thanks Herman for the heads-up on the TU114!
It's been installed and hope to have the info printed in the next few days, but I have a few questions.
It says the first flap setting is done at 400k/hr (215kts). You actually set the first setting at that speed? Touchdown is at 250k/hr (135kts)?
If so, okay, but seems really fast. Then they say to lower the gear at 350k/hr(190kts). Why not slow to 160kts and lower as you approach the glide-slope?
thanks for any input,

Why not slow to 160kts and lower as you approach the glide-slope?

I don't know much about the TU-114 (other than it's Russsian and "VERY BIG" .... in fact it was the worlds largest civil aircraft until the advent of the DC8-63) .... BUT .... I imagine that it might stall during the approach if the speed got too much slower.

That TU-114 wing has "one hell of a sweep" (meaning it's probably not a great idea to get too slow with it .... especially during approaches to landing) .... and remember too that it's 1950's technology !











That's about the best I can suggest/offer !

Actually .... just thinking a bit more about all this .... that wing sweep/speed thing etc !

Pretty much all the early Russian jets (despite the fact that the TU-114 isn't actaully a jet) from the TU-104 through to the TU-134, TU-154, and IL-62 .... all seem to have featured a similar very high degree of wing sweep.

And of course each these aircraft are also "VERY FAST" with it too !

Here's some images of the TU-104 ....

I couldn't resist the temptation to add a few more images of mine in action ....

TU-104











An interesting thing about the TU-104 is that the West .... never even knew of it's existence .... until one suddenly turned up at London during March 1956 (transporting General SEROV, head of the KGB). An old aviation photography colleague of mine (the late Colin BALLANTINE) actually witnessed and photographed it's arrival at London. This particular visit preceded 3 other TU-104's which also arrived at London during late April of 1956 .... and which transported the entire Soviet delegation to a UK hosted summit.

Interesting birds .... to say the very least !

35 degrees at the quarter-chord IIRC -- same as the Boeing 707's!

35 degrees at the quarter-chord

Actually .... I thought it was much more than that .... judging only from what it looked like pysically !

Hello louross;

The speeds used in docs section for the TU114 are basically just guidelines and are probably meant for MLW's.

I usually use a landing weight based on a 25% fuel load.

For the TU 114, I do apply the first flap retraction at 200 to 210kts.
I did not lower the landing gear until I reached the OM of the ILS, about 6nm. out and 160kts. ( never really needed it to slow down ).
I usually crossed the threshold at about 130 to 135kts and then pulled the power. You can try a little lower speed if you find that you float along too much.

Even though the TU 114 has swept wings, because of the huge amount of air flow over the wings produced by the props it will have a lower stall speed than pure jetliners.

I recall on the first few landings, I thought that I used up a lot of runway, but when I did the playback I saw that the actual contact came much sooner. That's how smooth this so called beast performs.
Try to stay a bit below the GS as you approach the threshold. I found the beast wanted to float a bit. Also the landings are very soft and it was usually difficult to know exactly when toutchdown occurred.
I hope this helps. Let us know how you make out.

PS. Mark...nice images of the TU 114 & 104

I recall on the first few landings, I thought that I used up a lot of runway, but when I did the playback I saw that the actual contact came much sooner

The reason for that is likely because there's no distinct touchdown WAV data within the SOUND.CFG .... and if it is there (in defult FS form) then it's possibly not communicating properly with the the default MSFS touchdown WAV samples in order to become sufficiently audible. I've seen quite a few FS soundpacks which suffer this same problem.

This's one of the details I've already fixed in my own TU-114 soundpack/s .... and as a consequence I do now get touchdown sounds immediately upon ground contact.

Good point Mark. I'll give that a try.

Herman

[louross]

Great point there, Mark.
Agree with everything you said, Herman. In fact, I had to confirm I'd actually landed by watching the airspeed indicator. (09R at EGLL). Let it roll out to the end, added pwr to 20%, and taxied to the gate.
Wellp, it seems that the TU114 was quite an amazing airplane. The FS version- one big circle aroung EGLL- didn't give me a great impression. Never saw an a/c that easy to fly! Used their notes to take-off, climb to 1500 meters, start a big circle back to 09R. Reaching 1500 puled the pwr lvrs back to what I tought was an appropriate setting, and was at 450. Statred the 180* turn, reduce lvrs, descended at 450 to 1000 and slowed to 400, set first notch of flaps and added a little pwr to maintain 400. Added another notch and gear, descended at 390, final flaps, pwr off, landed. Unbelievable!
With this in mind, I do like the newer DC6B pkg over at calclassics. Have been flying the B707-120 here at HJG, and am going to go to the -320B ADV. After some time with the -320, I plan to go back to the Dreamfleet 727. Of course, on the other hand, instead I might go to the ..., or ..., or ..., you know.

PERSONALLY .... I recommend "the latter choice" ;D

TRY IT .... YOU'LL LIKE IT !

mmmm, interesting, your choice, or suggestion, is. Why don't you like the second to last one?
